UNIVERSAL SEALING-MACHINE FOR KNOCKDOWN BOXES AND THE LIKE.

Specification of Letters Patent.

Patented Apr. 1, 1919.

Application filed May 23, 1918. Serial N 0. 236,212.

To all whom it may concern:

Be it known that 1, JAMES Q. Lnnvrrr, a citizen of the United States, residing at Ogden, in the State of Utah, have invented certain new and useful Improvements in Universal Sealing-Machines for Knockdown Boxes and the like, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to a universal sealing machine for knock-down boxes and the like.

The object of the invention is the construction of a relatively simple and eflicient machine for facilitating the closing and sealing of overlapping flaps of paper-board cartons or packages.

Another object of my invention is the construction of a machine, which is particularly designed for use in connection with the heavier grades of knockdown boxes made of heavy card-board, corrugated paper or the like, as well as boxes madaefihin ma terial; the machine being adjustable in parts for adapting it to the different thicknesses of the material of which the particular box being handled is constructed, as hereinafter fully described.

lVith these and other objects in View, the invention consists of certain novel constructions, combinations, and arrangements of parts, as will be hereinafter fully described and claimed.

In the drawings:

Fig. 12 is a fragmentary plan view of the hub and wheel portion of my machine.

Fig. 13 is a perspective view of a box or carton, as it appears after it has been folded and sealed by using my machine.

Fig. 14 is a perspective view of the supporting frame bar of the forming device.

Fig. 15 is a perspective view of the guiding plate of each forming device, which plate is fastened to the hub and wheel structure of my machine.

Referring to the drawings by numerals, 1 designates the legs of the stationary sup porting frame, which legs support the up per plates 2 of the frame, which plates 2 are connected by cross plates 3.

Mounted upon the cross plates 3 of the stationary supporting frame, is a stationary post that is provided with an enlarged head 5, in the upper portion of which head 5 are, preferably, positioned ball bearings 6 for facilitating the easy revolving of the hub and wheel structure of my machine.

The hub and wheel structure comprises the hub 7 provided with a central aperture 8, in which aperture 8 is positioned the stub axle or post 41 (Fig. 1), and extending from the hub 7 are spokes 9 and detachably se cured to the outer ends of the spokes 9 is an annular rim 10.

Secured to the upper faces of the spokes 9 between the hub 7 andthe rim 10, is a supporting fiat annular plate 11.

The annular plate 11 is provided, between each two contiguous spokes, with an aperture 12 (Fig. 12), and in this aperture 12 is positioned a fastening screw 18, which screw fastens the lower end of the upright bar 14: to the plate. Secured to the upper ends of the upri ht or vertical bars 14, is a ring 15; the ring 15 is attached to the upper ends of bars 1 1 by means ofithe bolt and nut structure 16. Attached to each vertical bar 1 1 (Fig. 2) near its lower end, at 17, are the lower ends of the inclined bracing bars 18; the upper ends of the-bracing bars 18 are positioned together and the upper ends of each two contiguous bars are fastened to ring15 by the bolt and nut structures 19.

The rotary carrier of my mechanism comprises the hub and wheel structure (including hub 7, spokes 9 and rim 10) and the vertical bars 14, ring 15 and bracing bars 18; the rotary carrier being mounted upon a stationary frame through the medium of the ball bearing carrying post and hub structure (post or stub-shaft 4 and head 5) hereinbefore described.

Having described the stationary supporting frame and the general structure of the rotary carrier, I now will describe specifically the plurality of forming devices carried by the carrier, although I will only spe cifically describe one forming device, for all of the forming devices are of the same structure, and are merely duplicated upon the rotary carrier, for the purpose or function as will be hereinafter clearly described.

The forming device comprises a guiding plate 20 (Fig. 15), which plate 20 has outwardly-extending ears 21, near its middle, each ear 21 being provided with a vertical aperture 22, in which aperture 22 is positioned fastening means, such as screws 23 (Fig. 3), and at each end of plate 20 are inwardly-extending flanges 24, which flanges 24 receive the inner, end of the foot or base portion 25 of the supporting frame bar 26 (Fig. 14). This frame bar is provided with a vertical standard portion 27, and the standard portion 27 terminates at its upper end in a horizontal outwardly-extending end 28, which end 28 is provided with a notch 29; the notch 29 adapted to receive a portion of the catch device, hereinafter described.

The frame bar 26 is provided with an elongated aperture 30, in its base. through which aperture 30 extends bolt 31, and mounted upon the bolt 31 is the winged nut 32. The base 25 of the bar 26 is slidably mounted in both sets of inwardly-extending flanges 24. The adjustability of the bar 26 upon the guiding plate 20. as indicated by dotted line 33 (Fig. 7), makes the forming device susceptible of accommodating different width boxes or cartons that are to be folded, as hereinafter described.

A socketed plate 34 is attached. by means of screws 35, to the base 25, at 36, 36, and this socketed plate 34 is provided with a setscrew 37 (Fig. 4) for clamping a detachable rod 38; this rod 38 can be raised or lowered a short distance in the socketed member 34 and held in this vertically adjusted position for permitting the forming device to accommodate different height boxes or cartons that are being formed thereon. Carried by the upper end of rod 38 is another socketed plate device 34, and this socketed device 34 is also provided with a set-screw 37, whereby a greater vertical adjustment can be secured, as will be obvious when one understands that by adjusting the device or socketed plate 34 upwardly on the rod 38 and securing the same in such adjusted position, the height will be increased.

Secured by means of screws 39 upon the plate 34, is a horizontal receiving former plate 40, upon which the knock-down box or carton 41 is fitted around, and then the side flaps 42 and end flaps 43 (Fig. 7) are folded down flat upon the former plate 40, and a piece of sealing strip 44 is placed across the meeting ends of the flaps (Figs. 7 and 13) and the clamping hinge presser plate 45 is moved into engagement with the folded and stripped end of the box or carton resting upon the former plate 40, and through the medium of the catch device 46, hereinafter specifically described, the presser plate is held tightly against the folded end of the box or carton until the sealed ends have been sufficiently dried.

The presser plate 45 is mounted between angle plates 47 (Fig. 6) and each plate 47 is provided on its side, with an elongated aperture 48, and on its top with an elongated aperture 49, and in these apertures 48 and 49 are screws 50, which screws are adapted to be easily loosened for allowing longitudinal adjustment of the presser plate 45 for accommodating larger or smaller boxes or cartons to be formed and sealed upon the forming device at the will of the operator.

It will be understood that after the desired length has been secured, by tightening the screws 50, the presser plate 45 will be retained in this adjusted position upon the angle plates 47. These plates 47 constitute leaves of a hinge structure, inasmuch as plates 47 are pivoted, at 51, upon the inner leaves or angle plates 52, which leaves or angle plates 52 are secured by fastening means, such as bolts 53, to the ring 15. Be sides being able to secure a vertical adjustment of the forming device as hereinbefore described, with reference to the socket plates 34 and 34 and the vertical rod 38 carrying the same, I am also able to secure a horizontal adjustment or enlargement of the forming device, for accommodating the different size boxes or receptacles, by reason of the outwardly and inwardly adjustability of the frame bar 26, as well as the former plate 45.

The catch device 46 comprises a hinge 54 having its inner leaf 55, fixedly secured to the top of the presser plate 45, and the outer leaf 56 of hinge 54 projects slightly beyond the outer end of presser plate 45, but in the presser plate 45, at 57, 1 form a notch or bifurcated portiom'which registers with the similarly constructed notch. 29 of plate 26 (Fig. 14). Slidably mounted in an aperture formed in the leaf 56 of hinge 54, bolt 58, which bolt is, preferably, square in cross-section, so that it will not rotate in the leaf 56, socket, or bifurcated portion 57 and in the notch 29. A disk 59 is secured, by

pin 60, upon bolt 58 near its outer end, and between the leaf 56 and disk 59, and mounted on the bolt 58, is a coil spring 61 for normally exerting an upward strain or pull upon bolt 58, so that when its squared, enlarged head 62 is hooked under the end 28 of bar 26, the catch device will not be accidentally detached from the bar 26; however, by reason of outwardly inclining the head 62, the operator can easily grasp the head and move it to an unhooked position (Fig. 7) for permitting the presser plate 45 to beswung to its open position (Fig. 7) for allowing a box or carton to be removed from or placed upon the former plate 4:0. On the outer face of bolt 58 is fixedly secured a stop pin 63, which prevents the bolt 58 from moving too far up on the leaf 56, by reason of the exertion always on the bolt, by the action of the spring 61; the bolt, when in its locking position shown in Fig. 1, is positively secured against any rotary movement by the further positioning of the bolt in the registeringsockets or notches in the end of the presser plate 15 and the frame bar 26.

The sealing strip carrying, cutting and gluing device comprises a supporting frame ca attached to the side of the stationary frame constituted by legs .1, sides 2, and cross bars 3, and secured to the supporting frame 64, at 65, is a hinged leg 66; the. frame 6% of the sealing strip carrying, cutting, and gluing device is further braced upon the main stationary frame by means of braces 67, connected to frame 64, at 68. The horizontal portion 69 of frame 641 carries a pan or receptacle 70, in which adhesive material is contained. The receptacle 7 O is fastened to the horizontal portion 69 by means of bolts 71 and attached to one end of the receptacle 70, are clamping lugs 72. Each lug is provided with a vertical opening and with an overhanging inner end 7 8 between which overhanging ends 73 of lugs 72, is positioned the frame 71. In the vertical aperture of one of the lugs 72 is positioned the gage 7 5, which gage is provided, at its upper end, with a horizontal extension 76; the gage being retained in an. adjusted position upon the lug by means of set-screw 77. In the vertical aperture of the other lug 72 is mounted the depending extension 78 of the water receptacle 79; the water receptacle 79 is provided with a nozzle 80 (Fig. 8) that permits liquid to be discharged from receptacle 79 upon the sponge 81 in the pan 82 carried by the frame 74 (Fig. 10). Integral with the frame 7 4, and, preferably, formed from the same piece of metal as the frame 7 1, by reason of the frame 74. being stamped, is a knife 83, which is provided with a corrugated cutting edge 84: (Fig. 8). A roller 85 is journaled upon the sides of frame 7 4E, and a supporting drum or reel 86 is also supported upon the frame 7 a near its outer end; wound upon the reel 86 is a sealing strip 87, which strip is passed under roller 85, roller 88, up in front of the corrugated cutting edge 8 1 of knife 83, and by reason of the gage 75 having been adjusted to indicate the desired length of the strip to be cut, for forming the strip er across the boxes or cartons (Fig. 13), the operator can quickly sever the desired strip 4 1 from the long sleeve strip 87 carried by the reel 86 and place this severed strip 44: upon the carton or box while it is in the position shown in Fig. 7, prior to clamping down the presser plate upon the carton, as is done, and clearly shown in Figs. 41.- and 5.

My sealing strip carrying, cutting, and gluing device readily adaptable for use by a right-handed or left-handed person, for all that the operator has to do is to remove the bolts 71, reverse the position of the receptacle 70 upon the horizontal portion 69 of the frame 64.- and then fasten the pan in the reversed position by placing the bolts 72. The receptacle 70 (Figs. 1 and 2) is readily accessible to the operator, if it is desired to further apply adhesive material to strip 87, by a brush for further facilitating the entire operation of sealing an end or bottom of a knock-down box or carton.

It will be understood that one operator can operate my machine, for the knock-clown boxes or cartons are received in a flat condi' tion, and are placed one at a time upon the forming devices, then the presser plate of the device is clamped upon the folded and sealed box or carton, and this operation is continued until all the presser devices are in use, and then by the time the first presser device that was used has traveled the entire circle, while the other presser devices have been filled, the adhesive material or glue will have sufiiciently dried for the removal of the first-placed box or carton, then a new knock-down box can be positioned upon the first filled former, and this operation continued indefinitely, as rapidly as the operator can work. The box or carton or receptacle, so closed at one end, can be passed on to the filling room, by any ordinary means, and filled, but I make no claim for the means for filling the boxes or cartons.

It is to be understood that I have invented a mechanism including a rotary carrier that is provided with a plurality of forming devices, each device comprising an adjustable holding or receiving means (former plate 40) in combination with adjustable clamping and pressing means.

In the appended claims, I use the word frame in a broad sense, to designate a base or the support or a standard.
